Abstract: A rotary shredder for waste materials has a pair of counterrotating cutter shafts, each of which mounts a series of spaced-apart disc-type cutters.  The cutters on one shaft extend into the spaces between cutters on the other shaft so that the cutters on the two shafts coact to shred material fed therebetween.  The two shafts are driven by a reversible radial piston hydraulic motor through a gear train arranged to rotate one cutter shaft at twice the speed of the other.  The hydraulic motor is driven by an electric motor-driven fixed or variable displacement pump.  A flow-reversing valve in the hydraulic motor control circuit controls the direction of fluid flow through the hydraulic motor,  The reversing valve is electrically actuated automatically by a fluid pressure-operated switch to reverse flow and the direction of rotation of the cutters to prevent jamming whenever fluid pressure in the motor circuit rises to an abnormally high level.  Upon detecting high pressure, the switch energizes a time delay relay which closes a relay contact to energize a solenoid which actuates the flow-reversing valve for a predetermined time period, after which the valve shifts to its normal position to operate the hydraulic motor in its normal directional mode to resume shredding,

Abstract: ABSTRACT OF DISCLOSURE          An automatic nozzle assembly for the dispensing of gasoline and similar liquids and of simple, efficient and low cost construction.  A stem extends into a housing and is actuated by a handle.  The stem extends through a check valve which closes a downstream opening in a valve seat secured in the housing.  A poppet valve is disposed about the valve stem and closes the upstream side of the opening in the valve seat to prevent fluid flow therethrough.  A yoke is disposed about the upper end of the poppet valve and balls are disposed in openings in the poppet valve and are forced into engagement with the top of the stem whereby the poppet valve moves upwardly with the stem and whereby the yoke may be moved to allow the balls out of engagement with the stem whereby the poppet valve may close independently of movement of the stem.  The movement of the yoke is controlled by the movement of a diaphragm which, in turn, is in communication with an annular groove in the valve seat which is, in turn, in communication with the opening in the valve seat through passages whereby a venturi is formed between the check valve and the opening in the valve seat to create a vacuum.  Normally, the vacuum is in fluid communication, through a vacuum tube connected to the valve seat, with the end of a nozzle tube connected to the housing such that, when liquid covers the end of the vacuum tube, the vacuum is applied to the diaphragm to cause movement thereof to automatically allow the poppet valve to close.

Title: Method and apparatus of forming and casting elongate, closed-ended hollow tanks
Inventor: HYRE ROBERT W
IPC: E02D23/00
Filed: 1977-06-23

Abstract: ABSTRACT OF THE DISCLOSURE         Method of an apparatus for forming (casting) closed-ended hollow tanks of preferably circular or modified circular section and of diameter and height (length) ranging from small up to one hundred feet in diameter, a thousand feet in length and weighing one hundred million pounds, such as are suitable for under polar-ice transport and thereafter storage of petroleum, and for other uses as well.  Forming and casting of such tanks is achieved preferably by slip-forming walls of concrete tanks (although conventional concrete forming and casting procedures and apparatus may also be employed), in ocean-depth water in which the tank is progressively submerged as forming and casting proceeds.  The apparatus for carrying out the aforesaid method comprises a floating barge assembly comprising two spaced-apart trussed-together barges and a submersible casting barge disposed in the space between said spaced-apart barges on which latter a slab of desired configuration providing the closed bottom end of the tank is first cast.  Towers of substantial height are provided on the mutually facing edges of said spaced-apart barges, atop each of which are mounted sheaves over which steel cables are trained, by which the casting barge and the tank as it is pro-gressively formed and cast are suspended in such manner that both casting barge and the progressively formed and cast tank are free to swing with a pendulum action, it being explained however that the suspending cables support but a small yet sufficient amount of the total weight involved to maintain the pendulum action.          The bulk of the weight of the concrete tank is supported first by the buoyancy of the casting barge and later by the buoyancy of the tank itself as it is progressively cast and lowered into the water.  As forming of the tank proceeds, the steel cables are alternately released and reset to lower the tank and casting barge into the water while maintaining the upper end of the tank at a relatively constant elevation above water level, as by admitting water or other suitable ballast to the tank interior in amount counteracting the buoyancy of the tank upon the latter becoming greater than its weight and that of the casting barge, etc.  Upon the tank being formed and cast to a particular length (depth), the submerged casting barge may be floated away from same, such without in any way interfering with further forming and casting of the tank should such be desired.

Abstract: A B S T R A C T         This invention relates to a method and apparatus for reproducing operating conditions in induced flow devices, such as carburetors and the like, and more particularly to a system for reproducing such operating conditions which may be used in testing systems designed to test induced flow devices.         In operation in such a test system, the apparatus of the present invention would cause a given air flow to flow through an induced flow device such as a carburetor, and then would cause the throttle plate of the carburetor to be rotated until the desired manifold vacuum in the carburetor is obtained, at which time the test of the carburetor could take place.  By providing a throttle drive controller to move the carburetor throttle at a speed which is proportional to the difference in the manifold vacuum actually present in the carburetor, and the desired manifold vacuum, a very rapid movement of the throttle plate between test points can be had, but at the same time a slow approach to the actual test point, to prevent over-shoot, is accomplished.         A continuous monitoring of the difference between the manifold vacuum in the carburetor, and the desired manifold vacuum, is accomplished by a continuous reading and comparing of electrical signals, in either a manual or computer controlled system, in which the two signals are first compared to determine which way the carburetor throttle must be moved to approach the desired test point, and then the actual difference between the two signals is computed to determine how many additional pulses must be supplied to the stepping motor forming part of the carburetor throttle drive controller to control the drive as described above.         The operations reproducing system of the present invention works equally as well computer or manually controlled, or with sonic or subsonic air flow measuring devices.
